    • A winching arrangement for lifting barges and the like from a water area in which a waterborne vessel is located. The present winching arrangement comprises at least two pairs of winches, each pair of which winches utilizes a common line to operate a block and tackle arrangement, with one of the winching mechanisms of each pair of winches being driven by a relatively high-speed motor and the other winch of the winching mechanism being driven at a relatively slow speed by a high-torque motor of greater horsepower. With the winches being connected to opposite ends of the common line of the block and tackle arrangement, with at least one pair of winches lifting one end of a barge or the like and another pair of winches lifting the other end of the barge or the like. The winches and the controls therefor, are so constructed that, as the waves or swells rise and cause the barge to rise faster than the ship or vessel on which the winching arrangement is located, the high-speed winches will take up the slack in the line as the barges are being lifted by the waves or swells and the slow-speed, high-torque motors will lift the barge onto the vessel as the waves or swells recede. The high-speed winching mechanism is held against retrogression by a one-way, releasable brake or the like, and the high-torque, slow-speed motor will continue to wind the winch line onto a winch drum until the barge or the like is at sufficient elevation that it may be moved into place or placed in storage, whereupon, the barge or the like is lowered into position on the vessel and this is repeated until the waterborne vessel is loaded. Reverse provisions are made for lowering the barges from the winch mechanisms into the water. Controls are provided for sensing the tension of the cable which controls the particular winch being operated.
    • {PG,1从水上船只所在的水域提升驳船等的绞车安排。 目前的绞车装置包括至少两对绞车,每对绞车利用一条共同的线来操纵一个车厢和一个滑车装置,其中一对绞车中的一个绞盘机构由相对高速的电机驱动, 绞车机构的另一个绞车由较大功率的高扭矩电机以较慢的速度驱动。 在绞盘连接到车体的共同线路的相对端部和滑车装置上时,至少一对绞车提升驳船等的一端,另一对绞车提升驳船等的另一端 。 绞车及其控制装置的结构,使得随着波浪或膨胀的增加,驳船的升降速度要比绞车装置所在的船舶或船只上升,高速绞车将会在 当驳船被波浪或膨胀所抬起时,慢速的高扭力马达会随着波浪或波浪的退缩将驳船提升到船上。 高速绞车机构通过单向可释放制动器等抵抗倒退,高扭矩低速电动机将继续将绞车线卷绕在绞车鼓上,直到驳船等 在足够的高度,它可能是{pg,2移动到位或放置在存储中,因此驳船等被降低到容器上的位置,并且重复该操作,直到水上船只被装载。 为了将绞盘从绞盘机构降低到水中,有相反的规定。 提供控制装置用于感测控制正在操作的特定绞盘的电缆的张力。
